About me

cropped-img_4750.jpg

PROFESSIONAL INTERESTS: I started my career by doing a substantial amount of fieldwork (plant ecology related) in many tropical regions such as Australia, Panama, Costa Rica and mostly Ecuador. Additionally, to complement the knowledge acquired in the field, I have been able to take several classes/workshops related to Population Biology, Community Ecology and Tropical Conservation in institutions like Smithsonian Tropical Research Institute, Missouri Botanical Garden and the Organization of Tropical Studies. In the last four years, including my Masters research, I combined my two interests: plant ecology and forests conservation, by doing my investigation in plant invasion ecology. More about my present position at USFQ here

DISSERTATION

The main objective of my dissertation was to use plant population biology and community ecology as frameworks to understand the mechanisms and ecological interactions that enable exotic plants to invade new habitats.

Specifically, my dissertation examined why plant species that are not necessarily common in their native ranges can become extremely widespread, vigorous and therefore noxious in new sites.

Using comparative and experimental approaches, my dissertation tested what are the relative individual and combined contributions of key ecological factors that enable introduced plant recruitment in new areas.

This research will contribute to our understanding of the mechanisms that lead plant invasions to success. Additionally, I want to start exploring the role of humans in biological invasion processes and their perception about the introduction of exotic organisms into fragile ecosystems.

My dissertation’s fieldwork was performed in the Galapagos National Park, Ecuador.

DISSERTATION OUTREACH

As part of my dissertation I also collaborated with the thesis research of two Ecuadorian students.

Maria Gloria Rivas did her Bachelor’s thesis at Catholic University in which she investigated (using greenhouse experiments in Galapagos), if Cedrela odorata is having an allelopathic effect that can potentially reduce natives’ and enhancing non-natives’ recruitment capacity.

On the other hand, Isabel Dominguez, (who is doing her Master thesis at Catholic University) is interested in understanding how plant species composition is affected when Cedrela is removed as a restoration strategy.

I want to give a special thank  to the Galapagos National Park and all their staff and park rangers who have been helping in the implementation of our projects in the Galapagos province.

Photos from the field:

Scalesia peducnculata flowers. Scalesia is an endemic tree for the Galapagos and since ~mid 1900’s it has been competing with Cedrela odorata, a non-native tree dominating novel ecosystems in the Islands.

COLLAB-NETWORK

ALSO and very important, this page seeks to start a database of investigators working in Ecuador, WHAT are they doing and their present affiliations. I will start presenting my close collaborators BUT, in the near future I expect to have a wider data base of many other investigators working in the country.

IF YOU ARE AN INVESTIGATOR in the life sciences (and related fields) and is WORKING IN ECUADOR, please send me your information as presented in the table above and I will include you in this list. So far this is a very basic attempt to “map” investigation efforts in the country. BUT I expect to expand this in the future to be able to analyze gaps in research and therefore promote collaboration to fill those gaps.
